Don't ever drop requested channels
Don't ever drop requested channels

Before moving to the ChannelDispatcher we got channels either through the
NewChannel(s) signal or as a result of requesting a channel from the CM. Now
that we've moved to the ChannelDispatcher, we only get channels that we should
handle through HandleChannels. So we shouldn't filter any of them.
